Flite and Ducking

[mspector]

Hi Again!

So in my project I am now trying to duck out background music (or whatever the user is currently playing) when flite speaks, and then bring the music back to normal volume when flite is done speaking. I am able to bring the volume down, but I am not able to get the volume back up. I think this has to do with the timing of the program and how long flite is speaking for. When I tried inputting a loop to stop the code until self.fliteController.speechInProgress is false, it is logged that the flite controller never enters the “finishPlaying” method. On the other hand, when I don’t have this loop and just log once flite has entered its “finishPlaying” method, it logs that it has entered it. Do you have any suggestions? I need to be able to know once flite is done, and then do something when its finished.

Thank you in advance!

Hiya,

Which version?

[mspector]

Version .913 I think…I downloaded the files back in January

If you think it would be worthwhile to update to the current version of OpenEars I can also do that for the new flitecontroller code.

I guess I would suggest that because the AudioSessionManager has been revised, which probably relates to your question. When you update, be sure to read the docs and be sure to no longer directly invoke AudioSessionManager, since that is now internal to the framework.

Okay I’ll work on the update and see if I can figure it out.

Downloaded the new version and I successfully got ducking to work by adding some code to audiosessionmanager and flitecontroller. Thanks for the new version! Working great so far!

That’s great!

Could I ask for the code use for ducking background music using flightcontroller?
